I am a recent CELTA (IH) garduate with very little experience who is looking to move to France to complete the DALF B4 level. I have 6 years of basic French behind me, but have not spoken, heard, or read the language for some 13 years.

I have a strong business background (6 Years as Director), 2 postgrad degrees and an MBA.

1. What are my possible options to achieve my goal and how long should I expect it to take with an elementary understanding of French?
